BOOSTER MOTOR SUPPORT Filed Sept. 26., 1928 INVENTR Cr M ATTORNEYS Patented Nov. 19, 1935 UNITED STATES NT GFF! E 9 Claims. (Cl. 105-138) This invention relates to booster motor supports and particularly to such supports for use with booster motors which are associated with pivoted trucks, especially trucks havingY four or more wheels, such as tender or locomotive trailer trucks. Y The nature, objects and advantages. of the invention may be best understood from a consideration or" the following description taken with the accompanying drawing, in which- Fig. 1 is a side View of a portion of a tender frame and truckwith a booster motor applied, certain of the parts being shown in vertical section substantially as indicated by the line I-I of Fig. 2 and others being shown somewhat diagrammatically.

Fig. 2 is a top view of the supporting structure, some of the parts being omitted and others being i shown diagrammatically, all for the sake of clarity, and

Fig. 3 is a section taken substantially on the line 3-3 of Fig. 1.

Referring now more particularly to the drawing, the center sills of the tender frame are indicated by the reference character 4, while the character 5 indicates the truck frame as a whole,

the truck being of the four wheel type in this case, with only one of the wheels 6 showing in 4the drawing. A booster motor I is operatively associated with the axle 8 on which the wheels 6 are mounted and extends therefrom away from the truck 5 below the sills 4.

II he truck frame has the usual bolster 9 which Ais pivoted to the tender frame by means oi the pin I0 in a well known manner.

The supporting mechanism of the present invention includes a bracket member II having spaced and apertured lugs I2 'secured to the truck bolster 3 at its side towards the axle 8 with which the booster 1 is associated. A supporting lever or arm I3 has an aperture at one end thereof vwhich is adapted to receive the pin I4 which passes through and extends between the spaced lugs I2. A nut I5 serves to secure the pin I4 in position. It should be observed that the arm I3 is configured and arranged to extend from the pin I4 upwardly and over the axle 8 and the associated booster motor 'I and is further of relatively wide and heavy construction, as clearly seen in Figure 2, so as to be substantially rigid at least in a horizontal plane. At its outer end the arm I3 is provided with a roller I5 which rides on the track or bracket I3, the latter being arcuately formed with the pin Ill as a center and secured to the center sills 4 as indicated at I'I in Figs. 2 and 3.

A strengthening member I8 may be provided for the track I6, the same being secured to the sills 4 in any suitable manner as by means of the rivets I3.

The booster motor 'I is supported by the arm 5 I3 by means of the link Eil having an eye 2I at its upper end adapted to be engaged by the pair of apertured lugs 22 which depend from the arm I3 near its outer end. A pin or bolt member 23, together with the nut 24, serves to secure the eye 10 2! in position between the lugs 22. The lower end of the link 2i] projects through an'opening 25 in the booster bed plate 26 and is provided with a supporting block 21 having an 'upper spherical bearing surfaceV adapted to engage a comple- 15 mentary concave bearing surface 28 formed in the bed plate 23 around its opening 25. A pin or key 23 secures the block 21 to the link 2U.

Above the bed plate 26 I have provided a semispherical member 33 having a circular shoulder 20 on its under side adapted to engage a corresponding recess or shoulder formed in the bed plate 2t around the opening 25, the same being indicated at 3| in Figs. 1 and 3. A bearing cap member 32 is provided with a concave surface on its under 25 side adapted to fit and bear on the spherical surface of the member 30. A spring 33 is arranged around the link 20 and reacts between the member 32 and an annular shoulder 34 formed on the link 20. 30

The last described parts of the supporting structure serve to retain the booster motor 'I in its normal supported position by yieldingly resisting any tendency oi the booster motor to move or jerk upwardly during operation. It should also 35 be observed that the rounded or semi-spherical bearing surfaces above and below the booster bed plate 26 are provided in order to ensure absolute freedom of motion when the track or other conditions cause the booster motor to rock somewhat 40 with respect to the center sills and the supporting arm I3.

The swinging operation of the arm I3, when the locomotive is taking curves, is, of course, obvious. 'Ihe arm I3 merely pivots with the truck 45 5 on the pin I0, the roller I 5 moving from side to side over its track I6 to support the booster'1 motor as it pivots with the truck. The arm I3, therefore, takes at least a portion of the lateral thrust of the motor, as the truck pivots, and thus relieves 50 strains which would otherwise be imposed on the axle 8 during pivotal action.

I claims- 1. In combination with a railway vehicle, a pivoted truck adapted to the application of a 55 booster motor, a booster motor supporting member secured at one end to the truck for horizontal movement thereby during its pivotal movement, the said member being restrained as against relative lateral movement with respect to the truck, and for upward and downward swinging movement with respect to the truck, means for supporting the other end of said member, and a booster motor suspended from the member intermediate its ends.

2.
